Answer:
the function that models the total inventory costs as a function of x is;
$( + (
)x )
Step-by-step explanation:
Given the data in the question;
cost of storing the shoes ( Holding cost ) = $ 3 per year
ordering cost ( Co ) fixed = $ 25 per order
cost of each pair = $ 5 per shoe pair
Total demand = 4500 shoe pairs
Total Inventory cost = Holding cost Ordering cost
so
Total Inventory cost = ( $ 25) +
× $3 × x
Total Inventory cost = $( + (
)x )
Total Inventory cost = $( + (
)x )
Therefore, the function that models the total inventory costs as a function of x is; $( + (
)x )
Using an exponential function, it is found that it's annual growth rate is of 4%.
<h3>What is an exponential function?</h3>An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, the card appreciates exponentially in value by 50% over 10 years, hence:
A(10) = 1.5A(0).
Thus:
1 + r = 1.04.
r = 0.04.
0.04 x 100% = 4%.
It's annual growth rate is of 4%.
